BAG-COUNTER FOR BAG-MAKING MACHINES.

Specification of Letters Patent.

Application filed May 18, 1911.

Patented Apr. 1, 1913-v Serial No. 627,938.

ject the provision of a. device that is actuated by the gearing of the bag-making machine and by working synchronously therewith will at all times count the same number of bags, so that the packages of bags made up will be uniform as to number, size and weight.

My invention furthermore has for its object the provision of two retainers for the bags as they are delivered from the machine, one of which is at all times in posivjacent to the upright E, on which is journaled a shaft 6, that is geared to the bagtion to receive the finished bags from the machine, and the other out of position, so that the bags previously delivered thereto may be removed therefrom by the operator to prepare it to receive the next lot of bags.

Another object of my invention consists in the provision of an improved construction of delivering-rolls for the bag-machine operated by the actuating-shaft for the automatic counters by which said rolls are automatically positioned to deliver to the proper receptacle for receiving the finished ags.

My invention will be described hereinafter and illustrated in the accompanying drawings, in which- Figure 1 is a side view of a conventional delivering device for a bag-making machine, showing my improved counter in position, the counter being in position to load the uppermost receptacle; Fig. 2, a similar view of the bag-counter and delivery-rolls, only, showing the lowermost receptacle in position to receive the bags; Fig. 3, a side view of the opposite side of the counter and delivery-rolls, showing the parts in the position shown in Fig. 1; Fig. 4, a view of the same parts shown in Fig. 3, with the parts in position shown in Fig. 2; and Fig. 5, a view of the lower portion of the counter, showing the parts in the same position as in Fig. 1.

In the drawings similar reference characters will be used to designate all the parts that correspond in the several views.

A indicates the delivery device of a bagmaking machine, consisting of drums B, C, and D, suitably journaled on standards E, and guide-rolls G, H, I and J, likewise journaled on uprights E, and delivery-rolls 1 and 2, journaled on arms 3 and4, pivotally secured to said uprights E.

K indicates a conveyer-belt extending from the bag-making machine (not shown) I and engaging drums B, C and D, deliveryroll 1, and guide-roll G, H, and I, while L indicates a short belt doubling with belt ,K over drums B, C, and D, then engaging delivery-roll 2 and guide-roll J, the two belts operating to inclose the bags carried vfrom the machine (not shown), while passing over drums B, O, and D to elevate them into position to be delivered to my counting device.

machine by any suitable gearing, so that it is rotated synchronously therewith.

7 indicates a beam slidably mounted in a slotted plate 8, secured to frame 5, on which is rigidly secured boxes 9 and 10, positioned to receive bags delivered from the delivery device heretofore described, being opposite the delivery-rolls 1 and 2.

11 indicates a cam-disk secured for rotation to shaft 6, one-half of the disk being concentric with the shaft, as shown at 12, while the other part of the disk is formed on an outwardly-extending spiral, as shown at 13, ending with a radial shoulder 14, connecting the widest part of the spiral 13 with the beginning of the concentric portion 12. By this mechanism, assuming that the foot of beam 7 is resting on the part 12 abutting shoulder 14 at the beginning of the rotation of the beam dropsoff of the spiral 13 onto lated as desired relatively to the speed of Copies of this patent may be obtained for fiv'ecents each, by addressing the Comm sinner of Patents.

the operation of the bag-making machine, so that the number of bags deposited in the boxes may be fixed, as desired.

15 indicates a rod slidably mounted in 'anism of a bag-machine, arms pivotallyseguide-brackets 16, secured to frame 5, 17 a bell-crank lever pivotally secured to said frame 5 and having one arm pivotally secured to the upper end of rod 15 and its other arm provided with a series of holes 18.

19 indicates an extension of arm 3, and 20 a link connecting extension 19 and the free arm of lever 17 being pivotally secured in one'of the holes 18.

21 designates a cam-disk secured to shaft 6 and positioned to engage the lower end of rod 15, said disk having one-half of its circumference cut on a spiral, as shown at 22, and the remainder cut, as shown at 23, concentrically with the shaft 6, and ending with a radial shoulder 24:, connecting the end of said concentric portion with the narrowest portion of the spiral.

It will be apparent that while the lower end of the rod 15 engages the spiral portion 22 the rod will be gradually raised and the angle of the delivery-rolls 1 and 2 to the perpendicular shifted, so that the bags delivered therefrom will be emitted on planes gradually approaching and finally reaching the horizontal; and that the horizontal emission of the bags will continue through one-half of the rotation of the shaft. Furthermore it will be apparent from the drawings that the positions of the two disks are ing the concentric portion 12 of the disk 11 to fill the uppermost box 9 the. rod 15 is engaging the concentric portion 23 of disk 21, and that when the disk 11 is rotated s0 that the beam is engaged by the spiral por tion of the disk, the rod 15 will drop off of v of the disk at all times.

perpendicular to insure delivery into said box 10.

25 indicates a spring secured to rod 15 and frame 5, normally. tending to actuate said rod downwardly and operating to hold the rod in engagement with the periphery Having thus described my invention, What I claim is 1. In combination with the delivery mechcured thereto, delivery-rolls journaled on ,said arms, one of said arms being provided with'an extension, a bell-crank lever, a link connecting one arm of said lever with the, H
